Glass Reinforced Epoxy (GRE,RTRP) Pipes

GRE pipes, with different ends for above or below the ground applications, are used in oil fields, industrial applications and desalination plants. They are also used for transporting drinking water, sewage drainage, civil and military airports, on-shore and off-shore, and on ships for naval applications.

Our GRE pipes are famous for being lightweight and deterioration resistance with a smooth core that reduces friction hence improving liquid flow. The poor thermal conduction of these pipes in comparison to steel pipes reduces the thermal isolation cost and temperature. The most compelling feature, however, is that after installation our GRE pipes do not require any maintenance.

GRE pipes and fittings are produced in diameters ranging from 25mm to 1200mm.

GRE products are designed for use in normal to aggressive environments with wide temperature range. The following are standard applications for GRE products

  • Oil field
  • Transporting drinking water
  • sewage drainage
  • civil and military airports
  • on ships for naval applications


  • Corrosion resistance from internal and external
    smooth core that reduces friction hence improving liquid flow
  • Do not require any maintenance after installation
  • Light weight
  • Smooth interior that reduces friction hence improving liquid flow
